> @mbaret thanks for the detailed RFC! i think my main questions here are whether or not this could be implemented in roughly two pieces similar to USMP: > > 1. a piece which could be reused if we e.g. wanted to attempt to apply this to non-Ethos-U kernels > > 2. the Ethos-U-specific logic. > > > I understand it may not make sense to integrate with AutoTVM--it might make more sense to wait til TensorIR has fully landed. but just curious to understand in planning terms what the lift might be. Apologies for the late reply @areusch. Due to some of the uncertainties around implementing this generically (Relay fusion/conflict with AutoTVM/deriving matrices), I think it's more pragmatic to have everything initially scoped just to Ethos-U. But within that implementation, all the truly Ethos-U specific logic is quite self-contained (pretty much entirely in the performance heuristics and matrix definitions). Therefore, should this need reusing in future we could probably lift it out of the Ethos-U namespace. I think this would be very doable as the cascader itself is quite well decoupled from the rest of the Ethos-U compiler, exposing only a TE Schedule -> TE Schedule interface. With some effort, although hopefully not too much, that interface could likely be tweaked to be TensorIR -> TensorIR. -- This is an automated message from the Apache Git Service.
